Hello All, this is my first post to say hello and introduce you to my Lancia Delta Integrale 8v.

I bought what I thought was a non-modified 8v turbo however I have since replace some of the worn/degraded hoses of the turbo, intercooler and inlet and the performance is now quite astonishing. The turbo boost pressure was, pre hose replacement, 0.6 bar and overbost to 0.9 bar, as expected, however since my samco hose replacement it appears that the boost pressure is achieving 1.5 bar (i didn't think this was possible? with an 8v) and with it a sharp increase in performance. I was planning on going through a path of modifications and upgrades but I'm not 100% sure what I currently have and the performance meets my expectations so I may change my aspirations to this regard.

A few problems I am having with the car.
1. Failed Radiator Fan - ceased to work recently, it appears that no power is going to the fan, temp sensor area at all (using a volt meter to detect) and am attempting to trace the culprit back to a fuse or relay but so far to no avail, have spend 3 hours on this to date - Any ideas would be welcome.

2. At around 3k rpm there is an engine tapping noise, no obvious vibrations, hoping this isn't something terminal (baring etc).

3. The car does not like re-starting after a drive, which makes getting petrol problematic. This may be due to the heat in the engine due to the fan malfunction? Any other ideas welcome.

Other than that the car has been great fun and exceeds my expectations.

To Do
1. Add in front bilstein suspension, I inherited these with the car. It has had the rear suspension put in already.
2. Replace more ducting, ignition leads, spark plus I cannot find the recommend ones B9EGV anywhere for sale (it's using the originals) hoping this may resolve the restart issue.
3. Fit under body brace to prevent shell cracking so I can load up harder in the corners and use the bilstein to full affect.

1. Car's been 'chipped'. Hence very high boost. Standard over-boost setting is 1 bar not 1.5....
2. Tapping is most likely rod bearings.. At 3000 the load is really coming on the bearings...

I'm working on an 8v Int at the moment. ECU technology is from the elegant and expert Nikola Radenkovic (founder of RP labs). The one I'm doing is fully loaded, no stone unturned. I have posted quite a lot about it on Facebook (https://www.facebook.com/GuyCroftRacing).

Yes I post here but currently due to pressure of work not as much as I'd like. Plus the uptake on membership has been er, disappointing.

I'd advise you pull the motor and start from scratch. There was a time the 8v stood unfairly in the shadow of the 16v units. Not so now, the 8v is incredibly rare and you must protect it. Consider that it won the WRC 3/4 times as often as the 16v...

Catch it in time will save the whole unit. Ignore me (I might be wrong) and you risk losing the whole engine.

GC, it is possible to see what You share in Faceboook without account ? I don't have account on FB and I don't want to have, but I really enjoy what You do and what You share.

I can make some photos of my OE pistons mods, OE rod mods etc. but this is not what you want to talk about. I am not a professional so I am not disapointed that my threads are boring for you (so members has another point of view about my threads).

I wanted to do a new thread about making a intake manifold for my engine but I am affraid that you don't want to talk about making, porting etc. of non GC parts, the same way as threads about OE stuff that I told before.

You done a lot of amazing job (it is worthwile to say that most of them was a free knowledge for us-members) and you are on the first place of race engine builders who give me a most important tips for all this stuff. I am sure that if you do not this I would not know about F/L engines even 1/4 that I know now.

Don't just post questions to me! Post for all readers, please. With pictures. Just do your best to add interest as well as asking questions. When I have time I will reply, look at the number of posts I have made here - and you will see I take that quite seriously. This a forum. It is not a one-man show to advertise GC.

I do my best to help folk, you included. I am sure you understand.

Please remember the terms under which membership was given to you, by me.

Just a quick follow up on the "chipped" boost. The boost picks up well at >2.5k rpm and peaks at an estimated 1.5 bar. The over boost light comes on when it meets the Integrale's criteria i.e in 2,3,4,5 gear and full acceleration above 2.25k.

Hi Gealing.
I enjoyed reading your post your car looks to be in excellent condition and they are brilliant little cars I have one myself.
I am very lucky as the engine being built in Guy's photos will soon be in my car. I will be updating my post very soon with lots of information that, reading about your engine problems, I am certain will be of use to you.
Im looking forward to seeing how you get on.

Thank you for the note, yes the car has been lots of fun... still a few things to do to get her into shape.

Looking to get the front Bilstein suspension put in over the next few weeks, plus I am going to take it the car to an engine specialist to get it checked over to make sure the small rattling noise is nothing sinister....if it is I may be going for an upgrade of the internals.
